The Commercial Court distinguished this case by the fact that a shipping plan was a “matter of routine” and that shipping plans had been agreed in the MRI trade in each of the previous two years (i.e. it was easy to be exploitable). On the other hand, in the present case, delivery dates are essential and are not easy to assess, given that no criteria have been defined and that there are many considerations relevant to the agreement of a delivery date.
